Specification of Letters Patent.

Patented Uct. 24, 191i.

Application filed December 3, 1910. Serial No. 595,454.

To all whom it may concern.-

Be it known that l, AXEL G. TULANE, a subject of the King of Sweden, anda resident of the city of Chicago, county of Cook, and State ofillinois, have invented certain new and useful Improvements in Lawn-Mowers, of which the following is a specilication.

My invention relates to improvements in lawn mowers and moreparticularly to an attachment therefor, the object being to pro'- videmeans whereby an ordinary lawn mower may efficiently cut the grass atthe edge of a lawn.

A further object of my invention is to pro* vide an attachment of thecharacter stated which shall be simple of construction and economical ofproduction.

Other objects will appear hereinafter.

With these objects in view my invention consists in the novelconstruction and arrangements of parts as will be hereinafter fullydescribed and more particularly pointed out in the appended claims.

My invention will be best understood by reference to the accompanyingdrawing forming a part of this specification, and in which Figure l is aperspective view of myl-improved lawn mower attachment, and F 1g. 2 is adetail perspective view showing a clamp employed in the attachment.

The preferred form of my invention as illustrated in the accompanyingdrawing comprises a flexible metallic band 1 which is adapted tosurround a driving wheel of the lawn mower as clearly illustrated inFig. l. The ends of the band l are bent at rightangles to the mainportion thereof and are connected by means of a clamping screw 8. Theband l is thus adjustably secured to the periphery of the wheel l andthe same may have any angular position thereon. In order to prevent thedriving wheel l from rotating on its journal a clamp 4t is providedwhich connects said driving wheel with the bail 5 of the lawn mower.Extending radially from the band l is an arm 6 which carries a laterallyextending journal 7 on which is rotatably mounted a traction wheel 8. Bymeans of the clamping screw 3 the wheel 8 may be revolved in a directionas indicated by dotted lines in Fig. l, thus varying the distancebetween the driving wheel l and the surface of the ground. ln thismanner the height of the grass cut at the edge of the lawn is varied.

The clamp -t comprises a hook l0 formed at one end thereof and anenlargement ll at the other end thereof, and arranged in a plane atright angles to said hook, said enlargement carrying a longitudinally.disposed thumb screw 12 as shown in F 1g. 2. The end of the thumb screwl2, which is adapted to contact with the handle 5, as indicated in Fig.l, is conical thereby preventing slippage.

From the foregoing construction it is apparent that an ordinary lawnmower may be readily changed for trimming the grass at the edge of alawn, the supplemental wheel provided in the attachment having avertical adjustment for varying the height of the grass cut, asaforesaid.

A lawn mower attachment of the construction set forth is not only usefulbut economical of construction.

While l have shown what l deem to be the preferred construction forcarrying my invention into effect, l do not wish to be limited theretoas there might be various changes made in the details of constructionand arrangements of parts described without departing from the spirit ofthe invention. Hence, l desire to avail myself of such variations andmodifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secureby Letters Patent is 1. A lawn mower attachment comprising a clampingmember adapted to be secured to one of the traction wheels of a mower; a

supplemental wheel carried by said clamp ing member; and means forsecuring said traction wheel against rotation, substantially asdescribed.

2. A lawn mower attachment comprising a flexible band adapted to besecured to one of the traction wheels of a mower, the ends of said bandbeing bent outwardly and connected by a clamping screw, a supplementalwheel carried by said band; and means for securing said traction wheelagainst rotation, substantially as described.

3. A lawn mower attachment comprising a flexible band adapted to besecured to one of the traction wheels of a mower, the ends of saidtraction Wheel, substantially as deneeted by zr clamping screw, asupplemental name to this specification in the presence of Wheel Carriedby said band; and n clamp two subscribing Witnesses.
